System DSN for a DB somehow got changed to master on that server for al teh users in domain. Now, Though I am able to change the DSN back to the db manually on my local machine, but it is still a chaos among all other users. I checked with the DBA and there was no change to the database or the server hosting the database. Please keep posted if someone finds the reason and how do you deal with such situation.Thu, 26 Jan 2012 16:39:10 GMTxitiz.barveRE: What would cause DSN file to change database to master?http://www.sqlservercentral.com/Forums/Topic706859-6-1.aspxNothing about the databases or the servers the database is on was changed.Wed, 29 Apr 2009 11:36:31 GMTWayneSRE: What would cause DSN file to change database to master?http://www.sqlservercentral.com/Forums/Topic706859-6-1.aspxAny changes to databases? renames?Wed, 29 Apr 2009 10:38:16 GMTSteve Jones - SSC EditorRE: What would cause DSN file to change database to master?http://www.sqlservercentral.com/Forums/Topic706859-6-1.aspx[quote][b]GSquared (4/29/2009)[/b][hr]Most likely, a change in the domain.[/quote]Agreed.

They need the help desk to make the changes.[quote]or the server.[/quote]What could have changed on the server to affect multiple users DSN entries? Since these are "System" DSNs, all of the settings are stored in the user's registry... and the user's can't get to that except through the "Data Sources (ODBC)" control panel applet.I just got back from visiting the users. They all share an access "program" (though only one can be in it at a time). They are using linked tables with the DSN. This needs for all of the users to have the same named DSN, with the same properties. Some of the users had a different name (space vs. underscore). However, several also had their "Change the default database to:" unchecked, and those had the "master" database selected (though dimmed).Once the DSNs are changed to be consistent, then there doesn't appear to be any problems.But, with many users, this is a PIA. I'm just looking for ways that all of these user's settings could have been altered.Wed, 29 Apr 2009 10:29:58 GMTWayneSRE: What would cause DSN file to change database to master?http://www.sqlservercentral.com/Forums/Topic706859-6-1.aspxMost likely, a change in the domain.

In sql, there is a domain group where the default db is set to their db. Yesterday users started having problems, where they weren't seeing the tables in their database. It ends up that somehow, [u]all[/u] users have had their dsn's changes from their db to master. The group login was still pointing to their db.What would cause this?Wed, 29 Apr 2009 08:22:29 GMTWayneS
